Spring Equinox in the Northern Hemisphere

Every place on earth experiences 12 hours of daylight twice a year, on the Spring and Autumn Equinox.The Sun is at its lowest path in the sky on the Winter Solstice. After that day, the Sun follows a higher and higher path through the sky each day, until it is in the sky for exactly 12 hours. On the Spring Equinox, the Sun rises almost exactly in the east, travels through the sky for 12 hours, and sets almost exactly in the west.

The March equinoxmarks the moment the Sun appears to cross the celestial equator – the imaginary line in the sky above the Earth’s equator – from south to north. After the March equinox, northern days continue to lengthen until the June solstice.
